I have concerns about the fact that people are obliged to answer questions about which some of them, not all of them.... Although I did say that Canadians were concerned, I must qualify that, because it does vary among Canadians. A good number of Canadians are concerned, which we know through studies and through complaints to my office.
If you put that together, feeling that the questions are overly intrusive on one hand, on the other hand with them being mandatory, then for many Canadians this is seen as an invasion of privacy.
I must point out, though, that others see it as a civic duty and not an invasion of privacy.
